Vixen claims Amanda's blood was in the bathroom and there was clear evidence Amanda had washed off Meredith's blood. If this was true, this would be damming slam dunk evidence. If the prosecution had such a solid piece of evidence at their disposal, why did the prosecution have to resort to telling numerous lies, suppressing evidence, using false documents, using smear tactics and using evidence with no credibility.
Exactly. The objective reality, of course, is that there is no such evidence.
The genuinely shocking thing, to me, of this whole area of the case is how fortunate we (and Knox/Sollecito) are to have the video recording of the inept CSI operation in this case. Because of that video, we know with 100% certainty exactly how the sink and the bidet in the small bathroom were swabbed for evidence by the incompetent team led by not-a-real-doctor (and most definitely not-a-competent-crime-scene-analyst) Stefanoni. We know with 100% certainty that each of the swabs that was taken for DNA and blood testing was obtained NOT by carefully "spotting" very small points on the surface of the sink/bidet (thereby only collecting evidence from very small, specific areas), but instead the incompetent doing the swabbing made long, sweeping motions across long lengths (up to 20-30cm long at times) across the sink/bidet.
This meant (obviously and self-evidently) that each swab picked up any and all matter along the entire length of this sweeping motion. It's therefore (and again obviously and self-evidently) clearly possible that any particular swab might contain physical evidence that had originally been present up to 20-30cm apart in the sink or bidet. It's therefore (and again.....) clearly possible that drops of Kercher's blood could have been collected on the same swab as DNA from Knox that might, for example, have been as a result of epithelial shedding from tooth-brushing, where Kercher's blood was at one spot on the surface of the sink, and Knox's epithelial DNA was as far as 30cm away on another area altogether of the sink's surface.
The shock is that if this video hadn't existed and been publicly available, the prosecution might have been able to hoodwink courts that the evidence collection from the sink/bidet had been done scrupulously properly, and that if Kercher's and Knox's DNA was present on the same swab, this must mean that both women's DNA had been lying intermixed on the surface of the sink (with the obvious implication that both women's DNA must have been deposited at the same time).
Looking back, I wonder why the police and prosecution didn't try to suppress the damning CSI video. Perhaps it was due to regulations stipulating that the full video must be made available. Perhaps it was because the prosecution and police actually didn't even realise how damning it was, and how inept and shockingly incompetent it made their operation out to be.........
